Abstract
Methods and apparatus for supporting on-demand content services, using conventional non-IP based VOD servers are described. The methods and apparatus of the present invention, through the use of a protocol converter and/or a content redirector, can be used to enable a conventional VOD server to supply content to a customer premise equipment (CPE) device which supports IP based content delivery and/or RSTP control of content delivery. The protocol converter of the invention can be implemented as an RTSP-ISA PROXY. The RTSP Proxy converts messages between RTSP (Real-Time Streaming Protocol) to the appropriate ISA protocol signal or another protocol format. The proxy module handles the conversion between these formats and converts a received signal, e.g. message, into the format required by the device which responds by implementing the operation requested by the signal.
